M'aiq thinks the title should be self-explanatory and he should not be able to explain what to do.
Have you ever had a sad moment in Skyrim that made you/almost made you cry (Your follower that you've had has finally died/a NPC that you loved died)? M'aiq almost cried when he first did the Companions quest-line when Kodlak is killed and then he almost cried tears of joy from reading Kodlak's journal. He will never forget that moment.
